The first one is a FAM-18 (F18-16) First Flight 06/30/1939 Southampton, England to New York.
I don't think the second one is a First Flight, as there is no indication as to the airline or the route.
The last one is a FAM-18 (F18-10) First Flight 06/24/1939 New York to Southampton, England.
Here's the site that lists them all with airplane photos and approximate values:
